A method and a device for treating at least a part of an individual's skin having a natural first polarization state. The method comprises the steps of applying at least two electrodes on the individual's skin at a distance from each other, and supplying a direct current to said electrodes to form an electrical potential difference between said electrodes on said part of the skin in order to bringing said part of the skin into a second polarization state, which is different from the first. The part of the skin is then suitable subjected to further treatment for example using cosmetics or pharmaceuticals. The invention can be utilized in the field of cosmetics and for therapy, and it can be used e.g. for accelerating skin care processes.
